NASA has developed the Black Marble, a daily calibrated, corrected, and validated product suite, so nightlight data can be used effectively for scientific observations. Black Marble is playing a vital role in research on light pollution, illegal fishing, fires, disaster impacts and recovery, and human settlements and associated energy ...
Python scripts to read, convert (GeoTiff), and display (QGIS) VNP46 files. If you do not have GDAL install, you can use the QGIS python console (Plugins -> Python Console) to run the script. Download the source code to convert NASA's Black Marble HDF5 product to GeoTiff.
We begin with the at-sensor TOA nighttime radiance (VNP46A1), along with the corresponding nighttime cloud mask, multiple solar/viewing/lunar geometry values (including moon-illuminated fraction and phase angles), and the daily snow and aerosol status flags.
The VNP46A2 Daily Moonlight-adjusted Nighttime Lights (NTL) Product. Both VNP46 products use the standard suite of VIIRS land products as input and are integrated as part of NASA's Black Marble processing chain which contains both daytime and nighttime branches.
